有人在要求扫描指纹后申请过英国签证的么？

我在卢森堡，因为老婆在英国工作，申请去英国的6个月多次往返的签证。现在的进度是，已经将Application Form和一大堆Supporting documents寄往巴黎的那个什么World Bridge的机构，就是专门办理签证的。这个机构的网站上说，申请表和材料递交后，还要安排interview和扫描指纹、拍照。但是没有说这两件事情是分开去办，还是一起办？如果需要先扫描指纹并拍照，那是等这个机构通知我去，还是我自己直接去？Interview是要通过什么方式预约？还是干等着对方通知我去interview？

这个world bridge的网站上交待的糊里糊涂，就是这么一段话，

After submitting your application you may be requested to schedule an interview with the Embassy after they have reviewed your application. Depending on workload, there may be a waiting period before the interview so bear this in mind when making travel arrangements to Britain.


Biometric requirements: fingerscans and photographs


All visa applicants must apply in person at the visa application centre in Paris to have fingerscans and photographs taken.


Fingerscans: All visa applicants must have their fingerscans taken. The fingerscan procedure uses an electronic scanner. No ink, liquid or chemical will be used and the procedure will take no more than two minutes to complete. If an applicant refuses to provide fingerscans, the application cannot be processed.


Photographs: All applicants will be required to have a digital photo taken at the time the fingerscans are performed. The photos will be taken with full face and without sunglasses, hat or other head covering unless the headcover is worn for cultural or religious reasons.


Interview procedures


Interviews are a normal part of the entry clearance process and where necessary provide Entry Clearance Officers with the opportunity to clarify certain parts of the application.


Should an interview be required then applicants will be offered the first available interview date.


我实在愚钝，搞不清楚了，请教在扫描指纹要求出台后办理过英国签证的各位：
